Intercom Label Receptacle Shutter and Lock Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intercom systems require specific tools to replace labels, which can lead to accidental damage of the intercom's electronic equipment and are not user-friendly for residents to update labels without professional assistance.
Innovation Solution
The intercom design allows for label replacement without accessing the interior, using a movable shutter and an electronic lock actuated by a shape memory material filament, enabling residents to replace labels electronically and securely, preserving the use of paper labels.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the transparent wall of each receptacle is fixed without any degree of freedom on the plate, then the intercom is protected against vandalism, but it becomes necessary to use specific tools to open the intercom for label replacement
Solution Approach 1:
The intercom housing is segmented into a fixed plate and a movable shutter assembly. The shutter can be independently opened to access receptacles for label replacement, while the main plate remains securely fixed to protect electronic equipment. This segmentation allows different security levels for different access points.
Solution Approach 2:
The movable shutter acts as an intermediary element between the external environment and the internal electronic equipment. It provides a controlled access point that allows label replacement without requiring direct access to the intercom interior, thus protecting electronic components while enabling maintenance operations.
2Ease of operation
If the intercom is opened to replace labels, then label replacement is possible, but direct contact with electronic equipment may cause involuntary degradation
Solution Approach 1:
The label replacement function is extracted from the main intercom housing by placing receptacles on the movable shutter. This allows labels to be replaced by simply opening the shutter without accessing the interior of the intercom where electronic equipment is housed, thus eliminating the risk of accidental damage to electronics during label replacement.
Solution Approach 2:
The movable shutter serves as an intermediary chamber that houses the receptacles. This intermediate structure allows users to access and replace labels without directly contacting the electronic equipment located in the main intercom housing, providing physical isolation and protection.
3Reliability
If specific tools are required to open the intercom, then security against unauthorized access is improved, but user-friendliness for label replacement deteriorates
Solution Approach 1:
The access system is segmented into two distinct mechanisms: the main intercom plate requires specific tools for opening (maintaining security), while the movable shutter can be opened without tools (enabling user-friendly label replacement). This segmented approach allows different security levels for different functions.
Solution Approach 2:
The shutter is designed with dynamic movement capability, allowing it to be opened and closed easily by users for label replacement. This dynamic element provides flexibility and ease of operation for maintenance tasks while the static, tool-secured plate maintains security against unauthorized access.

AI summary
An intercom system for a residence in which each receptacle (70) for a paper label (40) comprises: • a base (80) that mechanically isolates this receptacle from the interior of the intercom, • a perforated flap (86) movable relative to the mounting plate between an open position in which the flap allows the label to be replaced, and a closed position in which it prevents the label from being replaced, • an electrically operated lock that can be moved reversibly between a locked position in which it locks the perforated flap (86) in its closed position and an unlocked position in which it allows the perforated flap to move to its open position. The intercom system includes an electronic circuit capable of receiving a request to unlock the electrical lock and, in response, of controlling the electrical lock to move it from its locked position to its unlocked position.
